kaffir lime leaves — roughly torn into three
Kaffir lime leaves are low in calories and rich in volatile essential oils and antioxidants, particularly limonene. They provide minimal vitamins or minerals in typical culinary quantities but contribute beneficial phytonutrients and antimicrobial compounds.
About
Kaffir lime leaves are the aromatic foliage of Citrus hystrix (also known as papeda or Makrut lime), a Southeast Asian citrus species native to Indonesia. The leaves are distinctive figure-eight or hourglass-shaped due to a distinctive winged petiole (leaf stem) that resembles a second, smaller leaflet. They possess a deep green color, waxy texture, and intensely fragrant, floral citrus aroma with hints of lime, bergamot, and herbal complexity. The volatile oils concentrated in the leaves—primarily limonene and citral—impart a distinctive character that fresh lime juice alone cannot replicate.
Culinary Uses
Kaffir lime leaves are fundamental to Southeast Asian cuisines, particularly Thai, Laotian, Malaysian, and Indonesian cooking. They are most commonly bruised or torn and infused into curries, soups (especially tom yum), and braises to release their essential oils without the harshness of the bitter fruit pith. The leaves are also used in seafood dishes, fragrant rice preparations, and garnishes. Unlike the largely inedible fruit of the kaffir lime, the leaves provide a subtle, aromatic citrus note that enhances rather than overwhelms; they are typically left in the dish to soften during cooking or removed before serving if preferred for texture.
